The leaves are no more than a centimeter long. The flower head has many ray florets which are usually white, sometimes purple-tinged. They are 5 to 7 millimeters long. The fruit is an achene about half a centimeter long including the pappus, which is an elongated bristle surrounded by fused scales....read more on Wikipedia.
